1. Lovage

Name:Levisticum officinale

USDA Hardiness Zones:4 to 8

Size:3 to 6 feet tall and 2 to 3 feet wide

Conditions : Full Lord’s Day to fond shade ; average ground

Here ’s a multipurpose perennial with stature . Lovage is a member of the carrot class , and its tripinnate leaves , large chartreuse heyday umbels , and all other parts of the works are comestible . I toil the leaves into a slurry and use them in fall soups . The stems can be sugarcoat as a sweet delicacy with out - of - this - world flavor , and the seeds can be used as a topping for breads or savoury muffins . Stratify seed by chill them during winter and await outflow seedling with no fuss .

2. Persian stone cress

Zones:5 to 7

Size:7 to 14 in tall and wide

Conditions : Full Lord’s Day ; well - drained soil

This xeriscape recurrent demands to be notice . It resemble rosemary with its linear folio condition , but that ’s where the plants part company . The low - growing cast and relaxed habit of Persian stone cress plant make it easy to uprise in slopped , sunny , rocky pathways . If you could put up to fleece off the diminutive chartreuse seedpods , you could gain another explosion of blossoms in late summer , when few plants are blossom . Iranian Harlan Stone cress is a common passel on the Turkish hillside , but it is comfortable and dwell longer in New England . I have had great achiever stratify and sowing cum in winter and transplant the seedlings in spring .

3.Narrow-leaved inula

Name:Inula ensifolia

Zones:4 to 9

size:1 to 2 foot improbable and 1 foot wide

weather : Full sun ; moist , well - drained soil

This picayune stunner with lots of foliation pizzazz is gross for a cutting- or rock - garden edge . The midsummer perennial has burnished yellow - rayed flowers that are perfect for pollinators and onlooker likewise . And what a compounding to have the leaf and flower likewise shaped . Narrow - leave inula is well-chosen almost anywhere as long as it receives lot of sun . Unlike other species in the genus , it does not reseed in my garden and keeps its well - keep drug abuse and bod . Sow seeds indoors in spring at 70 ° F for germination in about two weeks , then bring seedling alfresco when the ground is viable .

4. Small’s beardtongue

Name:Penstemon smallii

Zones:5 to 9

Size:12 to 22 inches tall and all-embracing

Conditions : Full sunshine to partial shade ; fertile , well - drained grease

I have enjoyed studying and photographing the seed of this marvellous genus for many years and have also grown lots of plants from seed . With skinny to 300 metal money , Penstemonis one of the largest endemic genus of herbaceous plants in the United States . The tubular , dusty lavender flowers of Small ’s beardtongue strike a lovely pose as a front - of - border plant . Seeds sown in a soilless mix heated to 70 ° F will germinate in two to three weeks , and the plants will blossom the first season . This beardtongue is happiest in sun , although it will tolerate fond nicety . A truly wonderful native American wild flower , this industrial plant has a berth in every early - summer garden .
