There are more than 60 species of Porterweed (Stachytarpheta), low-growing annual herbs that attract butterflies. Because of its prominent blue flowers, the Stachytarpheta cayennensis is our favorite variety. The flowers typically wilt after a day. Fertilize twice a year to encourage continual blooming and cut back occasionally to prompt new growth.

We sell baby plants

Wellspring Gardens is the starter plant, AKA “baby plant” shop. We just get you started, so you get all the credit for raising your plants under your green thumb.

How tall are baby plants?

We aim to ship your plants when they’re 3-8” tall, though we often ship them taller than that.

What determines whether I get a 3-, 6-, or even 18-inch-tall plant?

The exact size of the plant we send you is variable on the time of year and how long we've been growing it out.

Honeysuckle Fuel brings out the blooms!

Named for our most popular flowering plant, Honeysuckle Fuel can help any flowering plant produce robust blooms.

Its power also extends to fruiting plants. When a plant is ready to start fruiting, use Honeysuckle Fuel to ensure its flowers turn into plump fruits.
