not crazy about the color yellow. Does anyone know if there is a pink perennial varity of this plant.

I found this hardy little snap growing near our back deck the first summer after we moved into this place five years ago. It gets slightly more shade than sun each day, and tends to get just a bit "leggy". I can deal with that, because it thrives on neglect and grows in uncultivated ground to act as a screen, covering the space between the deck and the ground. As another poster said, this plant is non-invasive - I wish it was!
I'm very pleased with this plant. The leaf structure is the same as the better-known varieties, but the size is slightly smaller. Relatively strong stems for a dainty snap. Mine are amazingly heat-tolerant, probably because of their overly-shady location and the moisture they (inavertently) get when I water my deck plants.

I love this plant, it's one of the first plants in my main perennial bed to bloom (mid april). Something interesting though, the first year I planted it it was pale yellow as it should be, but the next year and this year, it's pink, a nice pink, but pink. Not sure what accounts for the color change. I like it but i'm puzzled!

A very easy perennial to wintersow or direct sowing in ones garden. This hardy snapdragon from Spain blooms the first year from seed. The second year, the bushy plants send up dozens of creamy yellow flower spikes in early summer. It continues to bloom all summer if deadheaded occasionally.

Antirrhinum braun-blanquetii has a wider spread than annual snapdragons, so give it plenty of room.

I just love this perennial snapdragon! The plants bloom the first year from seed, but they are really impressive the second year when they grow large and bushy, and they bloom for most of the summer.

The flower color is a soft yellow that goes with anything.

Here in New Hampshire USA, I have both the yellow and also the bright orange/pink/redish color I think it may be named carnival and I got it from WFF. It has never been watered or fertilized and only weeded one time! The foliage is a pretty green color and similar to that of an annual snapdragon but softer. The stalks are quite strong and the plant has spread through both reseeding and has gotten bigger at the crown. It is not invasive! (Wish it was!)
