Ordered 3 of these along with 2 butterflyweeds (tuberosa)! antelope horns were you’re typically younger plant height which is fine as I have ordered from here in the past and it is expected with the pot size. Grows very horizontally just like the seeds deecription says and had perfect green leaves! no yellow which is good! I believe the plants have thinner stems at a younger age so please be careful with them! I was super cautious with mine, but they are happy plants!

Yes, you are correct! Antelope Horn is one of the smaller plants we sell simply because it is a slow grower the first year. This is related more to the growth pattern rather than pot size in the case of Antelope Horn. Like you said, it also tends to have thin stems the first year but next years growth will have much thicker stems. Green milkweed also tends to be slower the first year. However, we are able to ship almost all of our other plants between 8-24″ tall. If you need faster growing milkweed in the first year please consider Swamp, Aquatic, Common, Showy, Narrowleaf, or the annual milkweeds. Thank you very much for your review!
