I have 2 plants and they are the fragrance. We had a especially hard winter freeze -18 this winter and my plants took it hard. Does anyone know if I should cut them back, pull them up (to defeat)??? Usually by March they are beginning to get their leave and blooms, so far nothing. Any suggestions?

This plant is beautiful but is spreading all over the mountain sides in the San Bernardino mountains. The State of Calif. didn't realize it would take over like it has. I would like to know if this plant is safe around small children and animals.Please comment.

I live in Sedona AZ, at about 4200 feet (USDA Zone 7a). This plant does very well here even in full AZ sun (3:00 P.M. in mid summer - it's bright and it's harsh). I planted two Spartium junceum 2 years ago in 24" pots. They seem happy in pots, but I'm going to put them in the ground over the winter/fall. They have a wonderfully sweet aroma - so much so that I'm planting 5-6 more around the house. I haven't tried growing them from seed yet, but I will in the spring. If it works (assuming I know what I'm doing) I'll post info/results.

I planted spanish broom two plants side by side. One has beutiful yellow flowers an the other one is just green stems. They were planted at the same time. Not sure what is going on. But i like the plant even though it is a weed.

Emits a strong nasty smell when it blooms that causes me to have to wear a mask in my garden, annoying because I have lovely smelling roses. No wonder it is poisonous! Both my husband and myself are allergic.

2014 update:just read that this plant is now listed as a noxious weed in the west and is no longer sold. Pulling them out,if you have them looks like a great idea!

This plant is not invasive in Oklahoma; in fact, it has never produced any babies to give away. It has grown quickly since I planted it in 2004 and each year it gets more beautiful by rounding out, producing more yellow flowers, and its aroma is more lovely, like honeysuckle. It is an unusual looking plant because of its lack of leaves, which provides winter interest. I will try propagating it since many friends want one.

A marvelous plant with a distinctive and pervasive aroma and great color. The stems stay green and it adds winter interest.

I bought one of these at the local Walmart nursery (ups sorry!) It has done extremely well here in the high desert of california. The yellow blooms in spring are spectacular in that the whole shrub blooms. The fregrance is unmentionable but pleasant. I have seen them here locally get very big. I higly recommend having this and I am happy I have one growing so well. Happy Planting!!!
