Rated 5 out of 5 by from I've always had these plants. They are known to us as milkweed. I also have the all yellow blooming plant of same type. I save the seeds and plant them close to spring. They attract monarchs butterflies, hummingbirds and bees. I love them. Easy to grow.

Rated 5 out of 5 by from Beautiful & Hardy Be patient when seeding these indoors. The germination is sporadic over about three months. Once they've got a few leaves on them, I transition them outside. They're not fast growers, but they're heat, drought and light freeze tolerant. They produce clusters of brilliant red and yellow flowers. I rarely see butterflies on them, but they're always loaded with eastern black swallowtail caterpillars. I transfer the caterpillars to a fennel plant otherwise they'll decimate the asclepias. If a caterpillar does strip the plant to the stalk, trim it down to a few inches above the root and it'll start growing back in a month. They're also attacked by orange aphids on a regular basis, so keep a spray bottle of diluted dish soap handy. In spite of being a bit high maintenance, I absolutely adore these plants. It's very unusual to find a plant that produces beautiful blooms and tolerates central Texas summers yet persists throughout our "winters" without complaint.

Rated 5 out of 5 by from Robust Butterfly Attractor Love this plant. Even after 2 years of careless storage in a garage, the seeds germinated very well. I started them indoors and set them in a sunny window where they quickly grew big enough to be moved to the garden After I transferred them to my backyard, I made sure they didn't dry out during their first couple weeks outdoors, but have not had to spend hardly any time caring for them since. They grew tall and gained blooms within a couple weeks of being moved and have ever since been heavy with little flowers. Plant also does well in drier conditions too. When there is no rain for an extended period, the leaves begin to droop a little but still look ok, and they perk right back up with a little watering. Flowers do not appear to be affected by dry periods at all, which is awesome. And the butterflies love them! I have a monarch and a tiger swallowtail that hang out on my plants for a few hours every day. Highly recommended.

Rated 5 out of 5 by from Great plant for sunny gardens I grew these from seed this spring...I started indoors in March, and then moved them outside. They are the 'backbone' of my large flower garden since I ended up having so many plants. Their height is not overwhelming, and they have flowered all summer. The traveling monarchs laid their eggs on them this spring, and have now returned to feast on them on their way south. I will go to all the trouble of growing them from seed again this spring, since they were so easy to grow, bug free (except for monarch caterpillars), and a butterfly magnet!

Rated 5 out of 5 by from Great Butterfly Bush If you want a prolific bloomer that attracts lots of butterflies, this is the plant for you. I purchased a one gallon plant and had butterflies landing on it as I carried it to the backyard!!
