DESCRIPTIVE LIST OF FLOWERS. 153 
CARDIOSPERMUM,.—Batioon Vine. 
{From Greek words, signifying heart and seed, in allusion to itsround seeds, 
which are marked with a spot like a heart.] 
Cardiospérmum Halicécabum.—Balloon Vine.—Heart- 
Seed.—A halfhardy annual from the West Indies; a 
climber. The seed should be sown between the first and 
tenth of May, and the plant supported with brush ; four to 
six feet high. 
The plant is remarkable for its inflated mémbranous 
capsule, from which it is sometimes called Balloon Vine, 
or Love in a Puff. The flowers are white and green, 
without any claim to beauty. 
CASSIA. 
Cassia Marilandica.—Maryland Cassia, Wild Senna.— 
A hardy, indigenous perennial, four feet high, with yellow 
flowers, from August to September. Many of this genus 
are beautiful plants, but mostly tender; some species are - 
sensitive, and close their leaves in wet weather, or at the 
approach of night. 
CATANANCHE. 
Catananche cerilea,—Blue Catananche.—A handsome 
perennial, from the south of Europe, one and a half foot 
high, with brilliant blue flowers, in July and August. It 
has not proved perfectly hardy with me; but believe it 
will stand the winter better in a lighter soil than mine. 
It grows about two feet high. Vaillant explains the 
meaning of Catananche, by deriving it from two Greek 
words, and signifying necessity, that is to say, a plant 
which compels admiration. The name was employed by 
Dioscorides, to designate a plant used by the women of 
Thessaly, in philtres and love potions.
