The Penn Bentgrass Varieties
Professor Burton Musser developed Penncross in 1955, but thanks especially to the continuing efforts of Dr. Joe Duich, Professor Emeritus, Penn State University, and Crystal-Rose Fricker, president of Pure-Seed Testing, Inc., the Penn bentgrass family has developed the most trusted bentgrasses in the industry.

Penn A-1 has a very dark green coloration, fine leaf texture, tremendous heat and cold tolerance, very high density and superior disease resistance. It has very good winter color and spring green-up. It provides a superb putting surface and will provide an excellent playing surface on tees and fairways, too.

Penn A-2 has dark green coloration, excellent heat and cold tolerance, disease resistance and wear resistance. Penn A-2 has a very fine leaf texture and vertical growth habit, thereby providing an excellent putting surface. Works well in converting existing greens to a high-quality surface.

Penn A-4 is dark green with fine leaf texture, exceptional heat and cold tolerance, high density, disease resistant and aggressive growth habit. It provides a smooth grainless putting surface. Penn A-4 will also provide a good playing surface for tees and fairways. It is proven to be adaptable to various conditions.

Crystal BlueLinks Creeping Bentgrass had the highest turf quality, averaged across all locations, during 2006 NTEP fairway/tee trials. It has a different bluegreen color and has shown good resistance to brown patch and dollar spot. Crystal BlueLinks has also shown good heat tolerance.

Penn G-1 Creeping Bentgrass is medium dark green, has a vertical growth habit, fine leaf texture, very high seed count and very dense growth habit. It has proven to be adaptable to a wide range of growing conditions and management practices. Penn G-1 can be used for tees, fairways and greens.

Penn G-2 set new standards for smooth putting surfaces due to the vertical growth, fine leaf texture and high density. It can be used for tees, fairways and greens. Penn G-2 has shown good disease resistance, excellent heat and cold tolerance and the ability to compete against grassy weeds such as Poa annua.

Penn G-6 Creeping Bentgrass provides high-quality on fairways and greens. Its medium green coloration has demonstrated a high level of resistance to brown patch and leaf spot and it also has good resistance to dollar spot and fusarium patch. Penn G-6 has shown good growth in moderate shade and low-light intensity.

Seaside II Creeping Bentgrass provides a high-quality turf playing surface for tees, fairways and greens. It has shown very good drought tolerance and the ability to use effluent or water sources that have a salt level to 15,000 ppm, with a pH of 7.5 - 8.5. Seaside II has shown excellent resistance to dollar spot and other turf diseases.

Penneagle Bentgrass has medium green coloration and a non-aggressive vertical growth habit, which makes it perfect to use on fairways. The dense canopy and early spring green-up helps it compete against grassy weeds such as Poa annua. Penneagle can also be used for winter overseeding in the sunbelt.

Penneagle II Bentgrass provides an excellent playing surface for tees and fairways. It has a medium-fine, non-aggressive, semi-erect growth habit with a dark green coloration. Early spring green-up helps compete against grassy weeds such as Poa annua. Penneagle II can be used for winter overseeding in the sunbelt.

PennLinks II Bentgrass provides an excellent playing surface for tees, fairways and greens. It has a medium dark green coloration, with semi-fine erect growth habit and semi-aggressiveness. Increased density with improved disease resistance to dollar spot. Same good heat and drought tolerance as the original.

Nu-Penn Blend Creeping Bentgrass. This blend of Penn A-4, G-2 and G-6 bentgrass will provide an excellent playing surface due to the similar high density, fine texture, aggressive growth habit, improved disease resistance and heat and cold tolerance. Coloration is medium to dark green. Will out-compete grassy weeds such as Poa annua.

PennTrio Bentgrass is an obvious choice for tees and fairways. It combines the strengths of Penncross, Penneagle and PennLinks II. The certified blend has a wide range of climatic adaptability, due to the genetic diversity of the blend.

Pennway provides the broad genetic diversity required to create an excellent playing surface on various soil types. Contains Penncross, PennLinks II, Seaside II, Penneagle and Penn G-6. Has good heat and drought tolerance with good disease resistance. Pennway is also available as an uncertified blend.

Penncross has set the bentgrass standard since 1955. It has a medium green coloration and has rapid establishment. It is known for its aggressive, lateral growth habit and wide range of adaptability. Penncross has excellent resistance to dollar spot as well as other diseases.
