Herbaceous hardy perennials

This post is part of a larger body of work titled ”The Guerrilla Gardening Guidebook”. For the introduction and table of contents please …

Although some guerrilla gardens are intended to only last a year, some can last for a long time. Plant selection, coupled with continuing community support can make a community garden last for years with minimal maintenance.

A perennial is any plant that lives for three or more years, many live much longer. The garden flowers called perennials technically should be called herbaceous perennials because they lack the woody stems and branches of shrubs and trees, which are called woody perennials. Most herbaceous perennials die to the ground during winter, but their roots remain alive and send up new growth in spring. The tall tops of some perennials die in fall and the plant will develop ground-hugging rosettes of leaves that survive the winter. A few perennials, such as bergenia and epimedium, are herbaceous, but have evergreen or semi-evergreen leaves.

PinkWhiteColumbineMost perennials bloom for two or three weeks at a specific time of the year, and their foliage remain till frost. Some cherished perennials, such as threadleaf coreopsis and fringed bleeding-heart, are long-blooming, producing flowers for 8 to 12 weeks. Others, such as garden phlox and delphinium, can be encouraged to rebloom after cutting back the first flush of flowers after the blooms fade and before they set seed. Many perennials with short bloom times have cool foliage that lasts well beyond the flowers, leaf color and shape should therefor be considered as well.

Many perennials spread, forming larger clumps every year. Some fast growing plants need to be dug up and divided periodically or the plants will become stunted. Aggressive spreaders must be continually hacked back or they will take over the garden.SAMSUNG CAMERA PICTURES eding divided.

Perennials are cold hardy to different degrees, some can’t survive winters north of Washington DC, others flourish in Minnesota and the Dakotas. Some thrive in the hot and humid summers of the south, while others will simply wilt and flop over in anything remotely hot.

Living for only two years, biennials germinate from seed the first year and put all their energy into growing foliage and strong root systems. They often live through the winter as a rosette of ground-hugging leaves… The next growing season… They send up flowering shoots… Set new seed… And then die… But biennials can be unpredictable, not always sticking to the intended lifestyle. Some behave as short-lived perennials, flowering for two to three years before they die.

Epimedium, also known as Rowdy Lamb Herb, Barrenwort, Bishop's Hat, Fairy Wings, Horny Goat Weed, or Yin Yang Huo (Chinese: ÒùÑòÞ½), is a genus of about 60 or more species of herbaceous flowering plants in the family Berberidaceae. The large majority are endemic to southern China, with further outposts in Europe,[1] and central, southern and eastern Asia.
Epimedium species are hardy perennials. The majority have four-petaled "spider-like" flowers in spring. Many are believed to be aphrodisiacs, particularly horny goat weed.[2].


You can sheet mulch over it

Wild onion is a bulb. So pulling it doesn't help much. You can dig it all out but that is quite laborious. You can spray it with Roundup but it might come back next year - I'm not sure.
Try sheet mulching. See my description of it below under the thread "converting weed patch to veggie garden."
You'll need to dig very deeply and thoroughly to get out all the bulbs in any spot where you'll be making a hole in the sheet.
Consider leaving some patches of the wild onion. It's beautiful and hardy! You can plant annuals or herbaceous perennials over them. They will pop through every spring then as their foliage dies back your other plantings...


That, my love, is a pelargorium

This is a geranium:
The genera Geranium and Pelargonium are related - both are members of the family Geraniaceae but they are quite distinct. True geraniums, also known as cranesbills, (which refers to the shape of the fruit) for the most part have symmetrical flowers with ten fertile stamens.
Most Pelargonium have bilaterally symmetrical flowers with up to seven of the ten stamens fertile.
True Geraniums have a different seed dispersal technique than Pelargoniums. Geraniums fling their seeds away while Pelargonium seeds float away on the breeze and usually have a 'feathered ' end that Geraniums don't have
