kasvukohtadel sügava istutusaugu kaevamine eriti suure tähtsusega, kuna siis on võimalik selle põhja paigutada piisava paksusega drenaazikiht. Ka ei talu elulõngad mullapinna liigset kuumenemist suvise palava päikese käes, kuigi muus mõttes õitsevad elulõngad hästi üksnes täisvalguses. Mullapinna kuumenemise vältimiseks on vaja maapind kas multsida või kasvatada elulõnga juurel padjandtaimi MUID RONITAIMI Vähem levinud ronitaimeliikideks on veel · Hydrangea petiolaris -roniv hortensia (ei ole seni suudetud meil edukalt kasvatada; takistuseks eelkõige sobivate muldade puudumine, kuna vajab happelise reaktsiooniga, kuid seejuures kerget ja viljakat mulda) · Hedera helix -harilik luuderohi (külmaõrn ning kasutusel pigem toataimena; maapinda mööda roomavana on pidanud vastu saartel) · Aristolochia macrophylla -suurelehine tobiväät (külmakindel ning väga huvitav
September the fields and roadsides of the Great Plains erupt in a blaze of yellow as the sunflowers and goldenrods (also members of the sunflower family) make their presence known to the local pollinating insects. While many sunflower species may begin blooming in July, they are not as noticeable then as later on when they have grown up and over the surrounding vegetation. There are eleven species of sunflower recorded from Kansas. Most of them are perennials. Only the common sunflower and H. petiolaris, the Prairie Sunflower, are annuals. Identification of sunflowers can be very complicated because they frequently hybridize and even within species there is a high degree of variability. With a little practice, however, the most common species can be readily recognized. The Common Sunflower has a long history of association with people. Nearly 3,000 years ago it was domesticated for food production by the Native Americans. The seeds of the wild type of sunflower are only about 5 mm. long
