Updated

Pale-spiked lobelia carries small blue or white flowers on relatively slender stems. It tends to be short-lived, with overly rich treatment encouraging the stems to lean.

For Lobelia spicata, choose full to partial sun and moist to slightly dry soil. Recorded habitats include moist to mesic black-soil prairies; Savannas; Moist woodland and riverside meadows; Thickets; Bluffs; Limestone glades. Reported height: ¾–2¼ ft.

Its below-ground structure is described as taproot. Choose the permanent location with that root structure and the mature size in mind. Planning the surrounding space at planting time reduces the need to reorganize an established bed later.

Plant characteristics

Lobelia spicata (Pale Spiked Lobelia) has feathery blue to purple flowers that reach about 2' tall in mid-summer. Its flower color can vary widely from a white to a deeper blue-purple or even pink. This plant is typically found in low competition prairies including hill prairie, sand prairie, and glades.  It can also be found in sandy and dry savanna and open woodland areas.  Because it tolerates these varying site, it is an extremely adaptive and a beautifully compact plant for the home landscape.  Although beautiful, it can be fleeting as it is a short-lived perennial but reproduces readily in the correct location. 

  • Flower Color Blue/Purple - White - Pink
  • Flower Time July, August, September

    Plant Shipping & Care

    We want to ensure that our customers get what they want, a native backyard oasis. To do that, we need to follow a few simple guidelines and give you some information and pointers to make sure you get your plants delivered in a healthy state.

    As a reminder, you will receive an email to confirm your pickup or shipping window just before the plants are ready. See Order Fulfillment below for seasonal fulfillment windows.

     

    Choices to Receive Your Plants & Accessories

    • Retail online orders: Plant and seed orders ship only, except eligible trees and shrubs offered for pickup. Shipping charges are calculated at checkout.
    • Retail pickup — trees and shrubs only: Pickup is available by prior arrangement for eligible woody plants. Some container options are offered for scheduled pickup only. Check the selected product option and the cart pickup instructions before ordering. Pickup and shipped items require separate orders.
    • Wholesale orders: Plants, trees and shrubs are available for pickup by arrangement. Delivery can also be arranged for your order. Wholesale pickup is free. All seed orders ship, including wholesale seed.
    • Pickup locations and dates are confirmed by email. Please wait for confirmation before traveling to a pickup site. Our offices are not retail stores or nursery pickup locations.

     

    Order Fulfilment - When Your Plants or Other Items Will Be Ready

    We take orders all year long and seed is shipped all year, but we only provide the plants to you in certain fulfillment windows to ensure healthy plants.

    Wholesale Orders

    • Plant pickup and delivery are arranged for your order. Seed ships only.

     

    Retail & Website Orders

    • Seed Typically Ships Out Within One Week Of Order All Year Long
    • Typically, single species flats ship when ready, sometimes as soon as early to mid-April (depends on weather) through early-October.
    • Mixed species kits are batched and shipped as indicated on the product page.
    • If a plant order is placed while outside of the plant fulfillment window your plants will be reserved through your payment, however, the order will not be fulfilled and shipped until the following spring. We don't want to provide you plants when they won't be happy during the cold winter months. 
    • Early in the spring and later in the fall certain species may be dormant or partially dormant with brown leaves, however they will return to grow healthy next growing season.
    • Your order may arrive in several different shipments.
    • If certain plants within an order will not be available until a later date, we may choose to hold the full order until all are ready.  In certain circumstances, we may choose to send them in two separate shipments 
    • Fulfillment is always dependent upon plant availability.  We try our best but sometimes plants do not overwinter well and perish.  If a plant is on back order you will receive an email indicating the estimated shipping date.  If we can not provide the plant we will first notify you and give you an option of substitution or a refund of that individual species.
    • Plants are typically only packaged and shipped on Mondays to ensure they do not sit in the harsh delivery facility for extended periods of time over the weekend. You will receive a confirmation email once your delivery has been shipped and to estimate your delivery date.
    • Apparel & accessories are ready typically within one to two weeks. See product page for holiday shipping.

    Where We Ship

    Natural Communities ships native plants and seed from multiple supplier locations across the Midwest. Shipping coverage extends beyond our local consultation area; see the shipping map below. Availability and delivery options depend on the product and destination. Check the product details and shipping options at checkout, or contact us before ordering if you need help confirming coverage.

    Our on-site ecological consulting serves the greater Chicago region and southeastern Wisconsin, including the Milwaukee area. Consultations take place at your property by appointment. Our offices are not walk-in retail stores or plant pickup sites.

     

     

          What to Expect When Receiving Your Delivery

          • Your plants will be packaged with the utmost care
          • We will need to cut back certain plants prior to shipping. This seems counter-intuitive, however, the fewer leaves the less water the plants can lose during shipping, resulting in healthier plants for you. This also enables the plants to fit within the protective packaging and shipped safely.

           

             Shipments

            • Larger plant shipments will look similar to the picture below with a tray of your plants and a cardboard box to protect them during shipping.
